Hi ak8964, You can delete the “uv“ folder (C:\Users\userName\AppData\Roaming\uv) and reinstall comfyUI

多试几次，在中国你懂的，实在不行科学上网。我是大清早下载才成功的。

任务管理器中关掉你所有的Python(因为我也不知道哪个Python是comfyui的, 并且我当时没有启动扔和其他的python程序),或者重启重新打开comfyui就行. 原理应该是之前没关干净, 这个目录被其他进程占用.

I restarted comfy several times, clearing UV cache, restarting Comfy for the 10th time, running the update 3 more times, and finally it booted and is running v0.5.57, Hopefully is sticks this time, but even in past 10 minutes it reverted to v0.5.52 once.
